"On 4 November 1966, Bill C-243, "The Canadian Forces Reorganization Act," was introduced to amend the National Defence Act; the Canadian Army, the Royal Canadian Navy and the Royal Canadian Air Force, previously separate and independent services, would become one. Following debate in the House of Commons and further examination in the Defence Committee, the Bill was given third and final reading in April 1967, clearing the way for unification.
The Canadian Forces Reorganization Act came into effect on 1 February 1968. With that, the identity of the RCAF, its records and its achievements, were laid to rest in the pages of Canadian aviation and military history."
